Title: Direct current blocking amplifier
Inventor: ANSONII HIRUSON RICHIYAAZU
IPC: H03F3/04
Filed: 1990-05-07
Abstract: PURPOSE: To longitudinally connect circuits without forming an offset by connecting outputs of first an second differential amplifiers so that one amplification signal independent of the DC state may be generated on each of first and second balance signal input lines. CONSTITUTION: Input signals supplied to first and second signal inputs 52 and 56 are supplied to base electrodes of pairs of transistors TR 40 and 42 and TRs 44 and 46. Unbalance of the emitter current flowing to one of emitters connected to pairs of TRs is cancelled by contribution of the same current in the opposite direction of the other emitter connected to pairs of TRs. Though the DC offset caused by a preceding stage appears between first and second signal inputs 52 and 56, it doesn't change the DC levels in first and second signal outputs 68 and 70 at all. As the result, this circuit is longitudinally connected to another circuit and is coupled with respect to DC, and balance circuit design of simpler bias arrangement is realized.

Title: Ultrasonic body detector
Inventor: KATAYAMA SUSUMU
IPC: G08B13/16
Filed: 1988-05-14
Abstract: PURPOSE:To prevent detecting operation for a body from stopping completely by sending ultrasonic wave pulses at random at transmission intervals longer than specific transmission intervals. CONSTITUTION:When an external noise which has a relatively long period is received in a noise monitor period, a noise detecting circuit 7 detects the signal t3 and a signal interval t4 of the external noise N. Then when the signal interval t4 of the external noise N is much longer than a time obtained by adding a margin alpha to T1+T2 (detection processing period) (T1+T2+alpha<=t4), ultrasonic wave pulses A are sent at random a constant time t5 after the external noise N is received. Therefore, a body is detected in a period wherein it is predicted that no periodic external noise N is generated. Consequently, malfunction caused by the external noise N is prevented.
